LAKELAND, Fla. - Investigators located and are questioning the suspect of a hit-and-run of an 11-year-old girl, the Polk County Sheriff's Office said.

William Hull, 33, of Lakeland is charged with leaving the scene of a crash with serious bodily injury and tampering with evidence.

Tips led investigators to the man, the sheriff's office said.

Trinity Hamilton was walking westbound off the roadway and off the shoulder on Idlewild Street near Leslie Drive when an older model white pickup truck veered off the roadway, onto the shoulder and struck her at about 4 p.m., authorities said.

Hamilton fractured her jaw and dislocated her pelvis in the crash. She is expected to make a full recovery from her injuries, according to the Polk County Sheriff's Office.

"The child went into the ditch on the side of the road and the truck went back onto the roadway and behind the witness' car," the sheriff's office said.

The witness attempted to slow down to obtain a good description of the driver but the vehicle abruptly sped off in the opposite direction, the sheriff's office said.

Trinity was transported to St. Joseph's Children's Hospital in Tampa.

"From the first witness who saw the crash and rendered aid to the victim, to the tipsters who saw the photos of the suspect truck and pointed us right to it, we are so appreciative to our citizens who work with us every day to help us solve crime," Polk County Sheriff Grady Judd said in a statement.

Authorities are holding Hull in the Polk County Jail on $6,000 bond.
